Mag-E is the calming supplement in the Kohnke's Own range, built on protein-coated organic chelated magnesium with vitamin E, B1, natural yeasts and supporting nutrients. It is intended to take the edge off tension and spooky behaviour in horses in training or competition without dulling the horse — Kohnke's Own describes it as non-sedative and swab-safe. It works on the nutritional side of behaviour, so a horse that is sore, under-worked or badly fitted will not be fixed by a scoop of magnesium.
Four sizes, from a 425g starter pack to a 6.5kg bucket. Horses that are hot on grain often do better on a lower-starch ration alongside it — see Energy Gold for oil-based energy instead.
Benefits
- Chelated magnesium — protein-coated organic form
- Non-sedative — formulated to settle without dulling performance

Feeding Guide
Daily dose rates vary with bodyweight, workload and the rest of the ration. Follow the rate printed on the pack, and introduce any new supplement gradually over several days.
Kohnke's Own does not publish per-kilogram magnesium figures online. The guaranteed analysis is printed on the pack. Always confirm the current rules of your competition body before a swabbed event.
